REFLECTOR: fuel sight gauge

[Grigore Rosu]

I ordered mine from Velocity and they came with a 3-page installation
instructions.  Nothing else.

Despite being rather expensive ($126!), the gauge's instructions were poorly
written.

page 1: says where to install them and gives a way to do it, even though
page 3 shows two other possibilities, one for Vari Ez and another for Cozy,
which are NOT consistent with what page 1 shows; only the Velocity
installation is consistent with it.  Anyway, I liked the Cozy approach and
that's what I did.

page 2: says how to glue the two parts together, showing a "full-size gauge"
pattern which is actually significantly smaller than the actual gauge;
nothing about the LED.

page 3: shows three possible installations from the top.

Mine did not work at 3V at all.  Then I increased it to 4.5 V and the LED
started to lit (a bit).  I do not see any resistor on the wires in mine.

Does anybody know how to contact Vance?

Thank you,
Grigore
